Chapter 34 (1/2)

The next morning, the whole tribe became lively.

Yesterday, the guardian hunted and killed a bison alone, which was a great joy for the whole tribe. Having meat for two days in a row has further improved the reputation of the stone bear in the tribe.

After a cow is slaughtered, it can produce about 45% of the beef under normal conditions. However, unlike white people who believe in Jesus Christ, North American Indians don't eat the viscera of animals. They eat almost everything.

As the elite eater of the big eater Empire, the stone bear naturally did not taboo viscera. On the contrary, for the stone bear, the viscera of bison is more delicious than beef.

Therefore, the poor Bull Demon estimated that the horn, bone and hide of the cow could be preserved, and other parts of his body would be eaten by the Indians.

According to the instructions of the stone bear, the people in charge of slaughtering in the tribe left all the internal organs. These internal organs need to be well brewed before they can make delicious beef offal. However, stone bear has no time today, so after eating a few large pieces of beef stewed in white water and salt in the early morning, he moved around and began to prepare tools for steelmaking.

At first, Shi Xiong planned to use crucible to make pig iron, but then he thought about it. He felt that there was something missing in making steel with crucible.

Later, he remembered that if he used kaolin clay as a crucible, there was no graphite in the crucible, but the crucible steelmaking method needed a graphite crucible, which needed graphite and pig iron to react at high temperature, and finally steel could be made.

But what if I don't have graphite in my hand?

Later, Shi Xiong finally decided to use the steel stir frying method, but after thinking about it, he found that there is no thermometer, let alone a special thermometer used in the metallurgical industry, so it is not easy to control the temperature with the steel stir frying method, and it is easy to scrap a furnace of molten iron.

Finally, Shi Xiong thought of pouring steel.

This kind of steel-making method developed in the technology of stir frying is easier to control than that of stir frying, and can also better control the carbon content of steel.

The most important thing is that, in terms of the materials and conditions that I currently have, the steel pouring method is most suitable for my current situation.

Finally, after careful consideration, Shi Xiong decided to use the pouring method for the first furnace of steel!

In order to make steel with pouring steel, pouring steel furnace and blast equipment are essential. As for fuel, there is no more suitable fuel than coke. However, coke still needs special refining, which is troublesome, but this is not a problem.

As a cultural protection expert at the level of associate researcher, Shi Xiong once saw many steel pouring earthen furnaces in the Tang and Song dynasties in Sichuan Province and Henan Province. Later, he specially studied the use of these steel pouring earthen furnaces and how to pour steel.

With the development of science and technology, even the white people in Europe have not been able to make the open hearth furnace and converter, let alone the Indians. It will take more than 100 years before they can invent and make them. Now to make steel, we can only use the method of frying steel or pouring steel.

Under the current conditions of science and technology, the highest temperature that human beings can reach in metallurgy is no more than 1400 degrees Celsius, so it is almost impossible to produce high-quality steel.

However, the ancestors of China developed the pouring steel method on the basis of the frying steel method, which guaranteed the steel material.
